Oh, thanks for pointing out that grammatical oversight! (This is what you get for having 15 different versions of one chapter... :D) I've corrected it now, to read: 'would have laughed if it wouldn't have spoiled the moment.'

I'm so glad you found that paragraph hot! The very thought of watching Harry come makes me Snape hot. Whether he'll admit it or not.

And yes, this narrative structure is one of the plus points of co-writing. With each person taking on a different character, we can provide mirror insights into the same event, from different perspectives. It's like a wonderful game of hide and seek, and Atra totally THREW me with her chapter. Hee--you can ask her just how ASDLKJALKJLJSKLF I was after that frottage scene. I think my Snape lost all his marbles for quite some time, and I had to wait before I could respond with anything coherent. ;)
